[ecf-dev] Getting the hello examples to work with Zoodiscovery

["Patrick D." <pd4ecf@xxxxxxxxxxxxxx>]

Hello,

I'm trying to get the hello examples from the cvs to work with Zoodiscovery. After basically trying out all combinations of flavors, properties, ServiceInfos, DiscoveryAdvertisvers and DiscoveryLocators from http://wiki.eclipse.org/Zookeeper_Based_ECF_Discovery, I just can't get it work.

I already tried to create a container and connecting to a Zookeeper server manually, different flavors and other things but everything failed in one way or another.

I'm guessing you just can't Zoodiscovery in the same way as the other discovery methods and you have to do all things manually.

In one of my last tries I got the servers to connect to each other, but it still didn't discover any service that I registered.

So I just started over (again) and trying to make very small steps towards a Zoodiscovery integration.

The first thing I did was downloading Zookeeper and the Zoodiscovery bundle from :pserver:anonymous@xxxxxxxxxxxxxxx:/ecf and log4j from Orbit. No problems here yet.
I then proceed to download the hello examples from :pserver:anonymous@xxxxxxxxxxxxxxx:/cvsroot/rt.

Starting the generic hello host and the generic, zeroconf hello consumer work fine. Everything works just as expected.
These products were used as a starting point. I added a dependency to zookeeper, zoodiscovery and log4j and modified the launching parameters to:

-console -consoleLog
-containerType ecf.discovery.zoodiscovery

-containerId zoodiscovery.flavor.standalone=127.0.01

Starting any of the two products now results in the following output:

Any hint in the right direction is greatly appreciated!
